ML/invention re'latesfparticul arly' to wear.

ournallboxess of'` locomotives and; yanalbgous constructions-- l My'- primary'object is-to provide a wear- /plate adapted to be interposed between the journalbox andwheellhub, the .wear-plate bein@ adapted to be removedw1thout-ld1s-- memlberment. t The invention is particularlyapp'llcabl where the wheel is located outside the journalfbex, .asalta engines,l locomotives,- tenders,

etc. 4

The invention is illustrated 1n its preferred embodiment in the accompanying drawings, in'which-' X'Figure 1 represents a horizontal sectional view of a journalbox equipped with -a wearplate in accordance with. my invention, the

y section being takenas indicated at linel of motive wheel and axle brokenly; Fig. 2,'

Fig. 2, and the view showing also a .locoa vertical section taken as indicated atline 2 of Fig. 1; Fig. 3, a broken Avertical sectlon taken as indicated atline 3 of Fig.2; Fig. 4, an inner face view of my improved wearplate; Fig. 5, an edge elevational view of the same; and Fig. 6, a plan view of the same. l

In the construction illustrated, A represents an engine or locomotive wheel secured to or mounted on the c nd of an axle A, B a journal-box; and C my improved wearplate,l removably interposed between the wheel-hub l and the journal-box.

The journalbox B, sometimes called the driving-box, is fitted with the usual brass 2., which rests'upon the axle, and has the vusual cellar 8 adapted to contain lubricant.

It is common to removably secure the cellar 3 between the downward extensions l of the journal-bomby means of cellar-bolts 5.

The general form ofmy improved wear plate is shown in Fig. 4. It comprises a flat plate 6 adapted to afford a facing for the outer end of the journal-box. `rlhe plate 6 is'reces'sed centrally from its lower edge upwardly, as indicated at 7, the recess ter minating in asemi-cylindrical upper wall 8 which conforms to the lupper half of the Vaxle Al. The: plate 6 is provided at its lateral edgeswi'th inturned'llanges 9. VThat Lis, the flanges 9are turned away from -the wheel. The flanges 9 embrace the flanges 10 with which the'journal-box-B is providedat. its outer end; and the flanges 9 are equipped on their inner faces with flanges 11 vwhich* engage grooves l2 with which the flanges 10 areprovided in their yvertical edge portions. Thus, itV will be seen that the wearlplate is connected to the journal-box by vertical guides, which en- .able the wear-plate to be removed by a verti` cal movement. It ispreferred Ato equip l the'upper end of the plate 6 with an inturnedfsegmental lange13, which conforms 1n curvature to the curved upper-.surface 14 gf.. the outer. cross-flange 15 of; the journalox. y 1` As described, the plate 6 has downward extensions 16 whichfllank the axle A; and

these extensions, together with the llanges 9, may terminate somewhat below the cellar 3 of the `journal-box, thus enabling the sav flanges 9 to be provided at their lower ends with perforations 17 which aline with' perforations in lugs 1 8 and 1-9 with which the cellar 3 Vand the downward extensions 4 of the journal-box are provided at their lQwer portions. Thus, the outer cellar-bolt 5, suitably lengthened according to necessity, may be employed to secure the wear-plate against working upwardly in its guides.

The wear-plate may be of brass, or other material suitable to withstand the wearing action of thehub, due to thrust of the axle.

It will be noted that the outer face 2O of the wear-plate alfords a wear-surface which contacts with the Vertical innerface of the hub.

By providing for the removal of the wearplate by a movement of withdrawal in its own plane, preferably by a vertical movement, the wear-plate may be removed without dismembermeut of the locomotive ortender, as the case: may be. That is, it is unnecessary to drop the axle out of its bearing `in order .to enable a new wearing-surface to lne-applied to the outer end of the Journalbox. In accordance with my improvement,

the wear-plate may be removed at will and replaced by a new wear-plate with great facility; or, the wear-plate may be removed and re-faced and then employed again.

To those who are familiar with the great loss of time and large expense to which rail- Way companies are now subjected to provide against play between the wheel-hub and journal-box, particularly in locomotive construction Where theend thrust of the axle is at times enormous and the Wearing therefore large, it Will at once be appreciated that my invention is of the utmost practical importance and adapted to effect a. v-ery great saving in operating expenses.

The foregoing detailed description has been given for clearness of understanding only, and no undue limitation should be understood therefrom, but the appended claims should be construed asbroadly as permissible in view of the prior art.

What I regard as new, and desire to se-v cure by Letters Patent, is:

l. A Wear-plate for the purpose set vforth, comprising a plate having its lower edge recessed centrally to accommodate an axle, saidplate provided with lateral flan es equipped on their inner surfaces with gui er tenons adapted to slide in lateral grooves at the outer end-portion of a journal-box.

2. 'The combination with a journal-box y having the lateral vertical surfaces of its outer end portion provided with guidegrooves, and a vertically sldable Wear-plate having its lower end recessed to accommonal-box and equipped on their inner surfaces With guide-tenons engaging said grooves,

l and a bolt connecting said flanges to the lower portion of the ournal-box.-

3. A Wear-plate for the purpose set forth,

comprising a plate having its loWer edge recessed centrally to accommodate an axle,

said plate lprovided with lateral anges having their inner surfaces equipped With guide-tenons adapted to engage grooves in the lateral vertical surfaces of the outer endportion of the journal-box, and a-segrnental flange at the upper portion ofsaid plate adapted to overlie a portion of the journal box.
